Crew pro Posted August 31, 2013 Crew Posted August 31, 2013 (edited) Hey guys, just wanted to give drop some info on Elmors latest project Elmor has created a seriously handy little I2C controller he has named eVc. eVc connects via USB to a control computer and the eVc software allows control over nearly any graphics card that supports I2C. The controller works by interfacing with the PWM controller and allows adjustments such as voltages, current limits, load line and power states. This tool opens up lots of possibilities such as adjusting voltages on the fly. We have recorded a short demonstration on how eVc works and then taken an AMD 7790 subzero to see how eVc can open up clock frequencies when the GPU is subzero. AMD 7790 @ 1600 MHz, not bad! For more information you can check out the eVc homepage over at elmorlabs - http://elmorlabs.com/index.php/evc/ Attached is the link to a short video I've recorded to show how it works Edited August 31, 2013 by Christian Ney Quote
crustytheclown Posted August 31, 2013 Posted August 31, 2013 So this is the next step on gpu oc... AWESOME work!!! Quote
K404 Posted August 31, 2013 Posted August 31, 2013 Video link is broken, but this looks like it has a lot of potential! Jon..... is support for the NCP5388 and 5395 possible? Those two controllers make GPU benching much less fun. Quote
TaPaKaH Posted August 31, 2013 Posted August 31, 2013 will this device also work with eVGA's Epower? Quote
elmor Posted August 31, 2013 Posted August 31, 2013 It's still in the development phase since I'm a bit busy with other things at the moment, but in a month or two it should be possible to make them available on a bigger scale. Video link is broken, but this looks like it has a lot of potential! Jon..... is support for the NCP5388 and 5395 possible? Those two controllers make GPU benching much less fun. NCP5388 doesn't have a digital interface, just external VID control. Not sure about NCP5395 but NCP5392 doesn't have it either so I'm quite sure there is none on the NCP5395 either unfortunately.

elmor Posted August 31, 2013 Posted August 31, 2013 will this device also work with eVGA's Epower? Yes that is very likely. Quote

elmor Posted August 31, 2013 Posted August 31, 2013 Shame, but thankyou for the info! VID-mods are quite simple, what is the issue with those VRMs? Quote
K404 Posted August 31, 2013 Posted August 31, 2013 It's a pain. OCP and switch freq are linked and inversely proportional, so the pins need separated and modded separately. The PCB layout of cards using the NCP controllers are generally crap, so the VID components are sometimes (literally) all over the place. Then, there's OVP and droop to deal with. They're bollocks, basically Quote
Crabby Posted September 2, 2013 Posted September 2, 2013 Nice! I've fallin in love with this controller. Quote
Hiwa Posted September 3, 2013 Posted September 3, 2013 Nice device, saw it at comoutex works perfect... Good luck elmor to make it retail. Quote
dinos22 Posted September 3, 2013 Posted September 3, 2013 Download for hardware? My 5yo was asking me to download him xbox360 so he can play the same games as his cousin Quote
zeropluszero Posted September 4, 2013 Posted September 4, 2013 Laughed out loud in public awkwardly. Thanks for that massman. Quote
